Earthwork and related topics in Site and Infrastructure Subgroup are in which section range?

• A. 30-35
• B. 36-39
• C. 40-49
• D. 20-29

Answer: (A)

Understanding how MasterFormat numbers site work helps here. Earthwork and related site preparation activities are grouped in the lower portion of the Site and Infrastructure Subgroup, specifically in the 30-35 range. This placement reflects their role as foundational site work that precedes other site installations, so you’ll find excavation, grading, backfill, and similar topics under those numbers. The other ranges listed aren’t where earthwork topics within the Site and Infrastructure Subgroup belong, so they don’t match the placement for this content.
